What are mitochondria?
Sites of cellular respiration
What is cellular respiration?
The metabolic process that uses oxygen to drive the generation of ATP by extracting energy from sugars, fats, and other fuels
What is the endosymbiont theory?
States that an early ancestor of eukaryotic cells engulfed an oxygen-using no photosynthetic prokaryotic cell
What is an endosymbiont?
The cell that is engulfed that forms a relationship with the host cell in which it was enclosed
A cell living within another cell
How is the ancestor of eukaryotic cells (host cells) described by the endosymbiont theory?
Involved an nuclear envelope, an endoplasmic reticulum and a nucleus
How is the nonphotosynthetic eukaryote described by the endosymbiont theory?
Engulfing of oxygen-using non photosynthetic prokaryote, which, over many generations of cells, becomes a mitochondrion
How is the photosynthetic eukaryote described by the endosymbiont theory?
Involves a mitochondrion and the creation of a chloroplast by the engulfing of the photosynthetic prokaryote
Fill in the missing information.
A: Mitochondrion
B: Intermembrane space
C: Outer membrane
D: DNA
E: Inner membrane
F: Cristae
G: Matrix
H: Free ribosomes in the mitochondrial matrix
What are plastids?
A family of closely related plant organelles which chloroplasts are part of
What are two examples of plastids? Define them.
Amyloplast: colorless organelle that stores starch (amylose), particularly in roots and tubers
Chromoplast: has pigments that give fruits and flowers their orange and yellow hues
What is a peroxisome? What is its function?
Specialized metabolic compartment bounded by a single membrane
Contains enzymes that remove hydrogen atoms from certain molecules and transfer them to oxygen, producing hydrogen peroxide (H_2O_2)
How do peroxisomes grow in size?
By incorporating proteins made in the cytosol and ER, as well as lipids made in the ER and within the peroxisome itself
